    Hyper-V: properly handle loopback shares

    At the moment, the Hyper-V driver uses the UNC path of images
    stored on SMB shares, regardless if the share is remote or not.
    According to the MS docs, this is not supported for SOFS SMB shares.

    This is troublesome for the Hyper-C scenario, as Hyper-V will attempt
    to modify the image ACLs, making them unusable.

    The fix consists in checking if the share is local, and use the
    local path in that case.
